 CNC Drills |
 |
|
A drill is a tool with a rotating drill bit used for drilling holes in various materials. Drills are commonly used in woodworking and metalworking.
The drill bit is gripped by a chuck at one end of the drill, and is pressed against the target material and rotated. The tip of the drill bit does the work of cutting into the target material, slicing off thin shavings (twist drills or auger bits) or grinding off small particles (oil drilling).

Idea sticks it to a drilling problem
|
|
I often drill 1 /16-in.-diameter angled bleeder holes deep within workpiece cavities. Since standard-length drills don't reach, I use an extension made from drill rod. The trick, however, is securing the drills in the extension.
